FAQ
What is a submersible pressure transducer and how does it work?
A submersible pressure transducer is a type of sensor designed to measure the pressure exerted by a liquid column above it, typically in tanks, wells, or open bodies of water. It converts this pressure into an electrical signal—commonly a 4-20mA output—to indicate the liquid level. The L702 submersible pressure transducer 4-20mA offers accurate water level monitoring even in harsh submerged environments.
Can the L702 be used as a pressure level transmitter in water tanks?
Yes, the L702 submersible pressure sensor is ideal for use as a pressure level transmitter in water tanks. It delivers precise readings of water depth and is commonly used as a water tank pressure sensor in residential, industrial, and agricultural systems.
Is the L702 suitable for monitoring fuel or chemicals?
Absolutely. The L702 can be customized with compatible materials for chemical or fuel line pressure sensor applications. It’s also used as a tank level pressure sensor for diesel, petrol, and other fuels, ensuring accurate level measurement in hazardous or corrosive environments.
How is the sensor installed in a tank or well?
The L702 submersible pressure transducer supports threaded and flange mounting, making it easy to install in tanks, wells, or boreholes. It’s a plug-and-play solution that simplifies deployment in both new and existing systems.
What’s the difference between a level pressure transducer and a level transmitter differential pressure type?
A level pressure transducer like the L702 directly measures the hydrostatic pressure from immersion, ideal for single-point measurements in open tanks or wells. A level transmitter differential pressure type uses two pressure ports to measure the difference between top and bottom of a tank—more suited for pressurized or closed systems.
Does the L702 support real-time monitoring systems?
Yes. With a 4-20mA analog output, the L702 water level pressure transducer is compatible with most industrial control systems, SCADA, PLCs, and digital displays, enabling seamless integration into real-time monitoring and automation systems.
Can I use the L702 for seawater or groundwater monitoring?
Yes. The L702 submersible pressure sensor is constructed from corrosion-resistant materials like stainless steel and optional coatings, making it suitable for seawater, groundwater, and wastewater monitoring. It is commonly used as a pressure sensor for water level measurement in harsh environments.
